Abstract: Audio data is prevented from not synchronizing with video data when splicing. A first GOP of a video stream of a second program is spliced to a last GOP of a video stream of a first program. A first GOP of an audio stream of the second program is spliced to a last GOP of an audio stream of the first program. In this case, a gap amount PTS_FS required for synchronizing video data and audio data after the splicing is computed for each GOP. For the splicing processing, a gap amount PTS_FS_SPLYCE caused when the last GOP is spliced to the first GOP directly and the PTS_FS are used.

Abstract: A video receiving apparatus includes a receiving unit, a detecting unit, a determining unit, and a control unit. The receiving unit receives a video stream transmitted from a video distribution apparatus and to be reproduced by a video reproducing unit. The detecting unit detects an error occurrence position on the video stream in response to an error occurring during receiving of the video stream. The determining unit determines a reproduction start time based on the error occurrence position detected by the detecting unit and a position of a predetermined synchronization code in the video stream so that reproduction of the video stream is started before the error occurrence position. The control unit transmits a reproduction request including the determined reproduction start time to the video distribution apparatus.

Abstract: A computing system that has access to a streamed multimedia sample that is stored on a storage medium applies a zero-based presentation timestamp numbering scheme to the data packets of the multimedia sample, on-the-fly, and after each seek operation. After seeking to a desired starting point, the computing system reads ahead a maximum number of data packets within each media stream of the multimedia sample. A smallest timestamp (normalizing presentation timestamp) is identified and then subtracted from the timestamps of the data packets that are transmitted to the appropriate rendering devices, thereby creating appropriate presentation timestamps for the data packets for synchronizing the playback of the multimedia sample.

Abstract: According to one of embodiments, a method and apparatus for reproducing video and audio changes a playback speed for video and a playback speed for audio independently of each other. To provide an apparatus and method for controlling the playback speeds shortly before a period in which the video and audio should better be played back at a normal-speed, thereby to reduce the strange feeling the user may have as the playback changes from the high-speed playback to the normal-speed playback, a video signal and an audio signal are first isolated from a content and then demodulated. A playback speed is set for the video signal modulated, and a playback speed is set for the audio signal modulated. The video signal and the audio signal, each set to a playback speed, are output.

Abstract: A color difference processor recognizes the value of a color difference signal U and the value of a color difference signal V for each pixel from a color difference signal U/V, and respectively assigns the value of a luminance signal Y and the recognized values of the color difference signals U and V to the pixel. A reversing processor reverses, when the value of the color difference signal U and the value of the color difference signal V that are recognized by the color difference processor should be inherently recognized, respectively, as the value of the color difference signal V and the value of the color difference signal U, the recognition of the values of the color difference signals U and V that have been assigned to each pixel by the color difference processor. A conversion processor converts the value of the luminance signal Y for each pixel and the values of the color difference signals U and V for the pixel finally recognized, respectively, into the values of primary color signals R, G, and B.

Abstract: A system and method for providing a digital In-Flight Entertainment (IFE) system in a vehicle, such as an aircraft, that is capable of presenting a video program and associated audio in a synchronized manner to a large number of individual video monitors and speakers. The system and method employ processing operations in at least one decoder of the IFE system, to perform operations such as adjusting a local clock based on a master clock, setting a delay time in relation to a master clock, and adjusting video and audio playback based on the delay, to substantially synchronize playback of the audio and video data by the audio and video players, to thus eliminate or at least minimize the negative effects of source and load based jitter, network delays, clock drifts, network errors and decoder buffering differences, on synchronizing video and audio playback.

Abstract: An integrated circuit or system receives a bit pattern from a metadata, IPG, and or EPG signal. This bit pattern is then coupled to a circuit to provide a content control command to a recorder or to a processing circuit to generate a content control signal. In particular the bit pattern may be utilized in a manner to program, enable, or disable the generated control signal. Furthermore this content control signal provides resistance to a circumvention device. For example, the circumvention device is unable to remove sufficiently the content control signal, and content control is maintained.

A transceiver of the recorder device wirelessly transmits the timecode to a plurality of cameras. The cameras capture video data and audio data, and timecode managers of the respective cameras combine the received timecode with the captured video data and audio data to produce camera data. The cameras then wirelessly transmit the camera data to the recorder device for storage in a recorder memory. The recorder device may also receive and store PA audio data from a public address system. Furthermore, a computer device may communicate with the recorder device to perform various types of editing procedures on the stored camera data and PA data to produce edited data.
